Wall-mount temperature sensor EE451

RTDPTCbayonet

The EE451 measures accurately the temperature indoors and outdoors in building automation, HVAC and process control and enables weather-dependent temperature regulation. An optional display is available for the EE451 with analogue output. The T measured data is available on the voltage or current output, as well as on the RS485 interface with Modbus RTU. In addition, EE451 features a wide choice of sensing elements for passive T measurement. The compact and robust enclosure allows for easy and fast installation and unbiased detection of ambient temperature. An optional adapter and the free EE-PCS Product Configuration Software facilitate the setup and adjustment of the EE451.

Transmitter with "two-wire" technology receive the power from the process, and the signal is carried on return wire (closed current loop). With "three-wires" technology the power supply is separate from current output: 2 wires are the power supply and the third carries the signal.
